A comment on J-factor estimates of Segue 1 is in order. In order to
estimate its density profile parameters, we adopt a velocity
dispersion of the member stars based on Ref. [1]}.
However, there is a large uncertainty on what stars are regarded as a
member of the system, and depending on their inclusion or exclusion,
the estimates of the J factor of Segue 1 can be smaller by orders of
magnitude [2]}, [3]}. We caution that
our estimates are on an optimistic side, in a similar spirit of
earlier paper by the Magic collaboration [4]}.
Unlike earlier work including Ref. [4]}, however,
our new modeling adopting satellite priors systematically shifts the
best estimates of the J factors toward lower values, whereas our
results in the case of uninformative priors are consistent with the
results of the earlier studies.
